In the following, weight is declared as a mutable field. type person = { name: string; mutable weight: int };; Remark: As far as design is concerned here, one would consider the fact that a person's name isn't likely to change, but their weight is.

Initializing a record with mutable fields isn't different from a regular record initialization. let john = { name = "John"; weight = 115 };;

To assign a new value to a mutable record field, use the <- operator. john.weight <- 120;; Note: The previous expression has a unit type.

Generally tf.gather gives you access to elements in the first dimension of a tensor (e.g. rows 1, 3 and 7 in a 2-dimensional Tensor). If you need access to any other dimension than the first one, or if you don't need the whole slice, but e.g. only the 5th entry in the 1st, 3rd and 7th row, you are b...
